Abstract

Embodiments disclosed herein relate to a clamshell catheter lock device and method thereof. The catheter lock includes a first portion hingedly coupled to a second portion and rotatable through a plane extending perpendicular to the central longitudinal axis. The user may apply an opposing radially inward "clamping" force to transition the catheter lock to the closed position, thereby relieving any pressure applied directly to the patient. The catheter lock further includes a compliant sleeve coupled to an inner surface of the catheter lock and configured to slidably engage the catheter lock with the catheter in both the open and closed positions. The sleeve may engage the catheter with an interference fit to allow a user to position the catheter lock along the catheter and to hold the catheter lock in place until repositioned.

Description

Mechanical clamshell catheter lock

Disclosure of Invention

Briefly, embodiments disclosed herein relate to a "clamshell" catheter lock device configured to couple a catheter to a port stem. The proximally adjustable catheter allows for sizing of the catheter after placement. When placing the catheter and port assembly, the location of the distal tip of the catheter may be important to the efficacy of the treatment. For example, when a catheter is placed within the superior vena cava, the efficacy of the drug decreases if the distal tip of the catheter does not reach the target area. If the distal tip is advanced too far, arrhythmia may result. The distance between the distal tip of the catheter and the port may vary because the distance between the target location, the insertion site to the vasculature, and the location of the port may vary from patient to patient and from procedure to procedure. Estimating the catheter length prior to placement may lead to errors, thereby causing misalignment of the distal tip.

The proximally trimmable catheter allows the catheter distal tip to be placed at a target location before trimming the proximal portion of the catheter to the correct length. The clinician may then connect the catheter to a subcutaneous port or similar access device. However, securing a catheter to a port can be challenging. The connection must be leak-proof, especially under high pressure infusion. In addition, manipulating the catheter and port in the confined, moist environment of the subcutaneous access site can result in slippage of the access site, undue trauma, or misalignment of the distal tip of the catheter.

Disclosed herein is a catheter lock system, comprising: a catheter defining a lumen; a shaft configured to engage a lumen of a catheter; and a catheter lock configured to engage an outer surface of the catheter and secure the catheter to the shaft, the catheter lock comprising a body having a first portion hingedly coupled to a second portion and being convertible between an open position and a first closed position; a locking mechanism configured to releasably engage the first and second portions in the first closed position, and a sleeve coupled to an inner surface of the first portion or an inner surface of the second portion and configured to lock the catheter to the catheter in both the open and first closed positions.

In some embodiments, the body in the first closed position defines a channel having a diameter less than an outer diameter of the catheter. In some embodiments, the sleeve defines an inner lumen having a first inner diameter equal to the outer diameter of the catheter and a second inner diameter elastically deformable less than the first inner diameter. In some embodiments, the sleeve is elastically deformable to a third inner diameter that is greater than the first inner diameter. In some embodiments, the sleeve is formed of plastic, polymer, elastomer, rubber, or silicone rubber.

In some embodiments, the body further comprises a second closed position in which the diameter of the channel is greater than the outer diameter of the catheter. In some embodiments, the catheter lock system further comprises a latch mechanism configured to provide a mechanical advantage to transition from the second closed position to the first closed position. In some embodiments, one or both of the first and second portions are formed of a rigid or elastic material. In some embodiments, the sleeve is slidably engaged with the catheter in the open position. In some embodiments, the sleeve engages the catheter in an interference fit in the open position and is configured to be positioned on the catheter in a first longitudinal position and remain in the first longitudinal position until repositioned to a second longitudinal position different from the first longitudinal position. In some embodiments, the stem is in fluid communication with the port.

Also disclosed is a method of coupling a catheter to a shaft, comprising: slidably engaging the catheter with a sleeve of the catheter lock, the sleeve coupled to an inner surface of a first portion of the catheter lock body hingedly coupled to a second portion of the catheter lock body, the first and second portions in an open position; pushing the proximal end of the catheter onto the shaft; the sleeve is slid longitudinally along the catheter to align the catheter lock with the proximal portion of the catheter and the first portion is rotated relative to the second portion to transition the catheter lock from the open position to the closed position.

In some embodiments, rotating the first portion relative to the second portion further includes applying a first radially inward force to the first portion and a second radially inward force to the second portion opposite the first radially inward force. In some embodiments, the catheter lock body in the closed position defines a channel having a diameter equal to or less than the outer diameter of the catheter. In some embodiments, the sleeve defines a channel having a first inner diameter equal to the outer diameter of the catheter and elastically deformable to a second inner diameter that is less than the first inner diameter.

In some embodiments, the sleeve is elastically deformable to a third inner diameter that is greater than the first inner diameter. In some embodiments, the sleeve is formed of plastic, polymer, elastomer, rubber, or silicone rubber. In some embodiments, the method further comprises engaging a latch mechanism to couple the first portion and the second portion in a second closed position in which the catheter lock body defines a second diameter that is greater than the catheter outer diameter.

In some embodiments, the method further comprises engaging a latch mechanism to transition the catheter lock body from the second closed position to the first closed position. In some embodiments, one or both of the first and second portions are formed of a rigid or elastic material. In some embodiments, the sleeve slidably engages the catheter in the open position. In some embodiments, the method further comprises sliding the catheter lock in the open position along the catheter to a first longitudinal position, the sleeve engaging the catheter with an interference fit to retain the catheter lock in the first longitudinal position, and sliding the catheter lock to a second longitudinal position different from the first longitudinal position.

Also disclosed is a catheter lock system comprising: a catheter defining a lumen; a port comprising a stem configured to engage a lumen of a catheter; and a catheter lock configured to engage an outer surface of the catheter and secure the catheter to the shaft, the catheter lock having a body with a first portion hingedly coupled to a second portion and being transitionable between an open position and a first closed position, a locking mechanism configured to releasably engage the first portion and the second portion in the first closed position, and a sleeve coupled to one of the first portion or the second portion and configured to couple the catheter lock to the catheter in both the open position and the first closed position.

In some embodiments, the body in the first closed position defines a channel having a diameter less than an outer diameter of the catheter. In some embodiments, the sleeve defines an inner lumen having a first inner diameter equal to the outer diameter of the catheter and elastically deformable to a second inner diameter less than the first inner diameter. In some embodiments, the sleeve is elastically deformable to a third inner diameter that is greater than the first inner diameter. In some embodiments, the sleeve is formed of plastic, polymer, elastomer, rubber, or silicone rubber.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

The embodiments described herein relate to a clamshell catheter lock ("catheter lock") 100 configured to secure a catheter 90 with a shaft 60 or similar rigid structure. Fig. 1 illustrates a clamshell catheter lock 100 in an exemplary use environment, for example, coupling a catheter 90 or similar compliant tube with a stem 60 of a port 50. It is to be understood that port 50 is an exemplary medical device and that the embodiments disclosed herein may be used with a variety of medical devices that require a compliant tube to be coupled with a rigid rod to provide fluid communication therebetween.

In an embodiment, the port 50 may generally include a body 52, the body 52 defining a reservoir 54 in fluid communication with an interior cavity 62 of the stem 60. The port 50 may also include a needle-penetrable septum 56 disposed over the reservoir 54 and configured to provide access to the reservoir 54. In use, an access needle may extend percutaneously through the needle penetrable septum 56 and into the reservoir 54 to provide fluid communication therewith.

In an embodiment, the catheter 90 may include an elongate body extending longitudinally between a distal tip and a proximal end 94, and may define a catheter lumen 92. In an embodiment, the distal tip of catheter 90 may be disposed within the vasculature of a patient to provide fluid communication therewith. In an embodiment, catheter 90 may be pushed axially over shaft 60 to engage shaft 60 with an interference fit and provide fluid communication between catheter lumen 92 and shaft lumen 62. In embodiments, the catheter 90 may be formed of a compliant material, such as plastic, polymer, polyurethane, elastomer, composite, rubber, silicone rubber, or the like. In an embodiment, the conduit 90 may be configured to elastically deform and may extend over the stem 60 to engage the stem 60 with an interference fit and provide a fluid-tight seal therebetween.

In an embodiment, a catheter lock 100 may be attached to the outer surface of the catheter 90 and compress the catheter 90 onto the shaft 60 to further secure the catheter 90 thereto. The catheter lock 100 is particularly important to ensure that the catheter 90 does not accidentally disengage the shaft 60. In addition, the catheter lock 100 may secure the catheter 90 to the shaft 60 to allow increased pressure or increased flow rate therethrough without failure or leakage of the catheter 100/shaft 60 connection.

In an embodiment, as shown in fig. 2-3, the catheter lock 100 may include a body 110 having a first portion 112, the first portion 112 being hingedly coupled to a second portion 114 by a hinge 130. Hinge 130 may be a mechanical hinge, a living hinge, or similar structure configured to allow first portion 112 and second portion 114 to rotate relative to one another. In an embodiment, the first portion 112 and the second portion 114 may rotate relative to each other between an open position (fig. 2) and a closed position (fig. 3). The catheter lock 100 may also include a latch 140 or similar mechanism configured to secure the body 110 in one or more closed positions. Exemplary latch mechanisms 140 may include clips, barbs, pawl catches, ties, sutures, ratchet and pawl, zipper ties, over-center latches, combinations thereof, and the like. In an embodiment, the body 110 may be formed of a first material that provides substantially rigid or resilient mechanical properties. The body 110 may be formed of plastic, polymer, metal, alloy, nitinol, composite, combinations thereof, or the like.

In an embodiment, the catheter lock body 110 (fig. 3) in the closed position may define a channel 116, the channel 116 configured to receive one or both of a portion of the catheter 90 and the shaft 60 therethrough. In an embodiment, the diameter of the channel 116 may be equal to or less than the outer diameter of the catheter 90. In an embodiment, the diameter of the channel 116 may be equal to or less than the outer diameter of a portion of the conduit 90 disposed over the stem 60.

In an embodiment, the first portion 112 and the second portion 114 may be rotatable relative to each other between an open position and one or more closed positions by a plane extending perpendicular to the central longitudinal axis 80. Advantageously, as shown in fig. 2, the catheter lock 100 may be transitioned from the open configuration to the closed configuration by applying opposing radially inward forces, such as clamping forces, perpendicular to the central longitudinal axis 80. In this way, the application of an opposing "clamping" force relieves any pressure that may cause discomfort from being applied directly to the patient. In addition, when pressure is applied to the catheter 90/port 50/catheter lock 100 assembly, more control is provided to the user and slippage and undue trauma within the limited wet environment of the subcutaneous placement is mitigated.

In an embodiment, the catheter lock 100 may further comprise a sleeve 120. The sleeve 120 may be formed of a second material that provides flexible, compliant, or elastically deformable mechanical properties. In embodiments, sleeve 120 may be formed from plastics, polymers, elastomers, rubbers, silicone rubbers, composites, combinations thereof, and the like. In embodiments, the sleeve 120 may be coupled to an inner surface of one of the first portion 112 or the second portion 114 using an adhesive, bonding, welding, fasteners, combinations thereof, or the like. In an embodiment, the sleeve 120 may define an inner lumen 122, the inner lumen 122 configured to receive a portion of the catheter 90 therethrough and slidably engage the catheter lock 100 with the catheter 90.

In an embodiment, as shown in fig. 2, the sleeve 120 in an unstressed state may define a generally circular interior cavity 122. Note that as shown in fig. 1, 2 and 4A, the sleeve 120 is shown as a wire frame for clarity. In an embodiment, the diameter of the sleeve lumen 122 in the unstressed state may be greater than the outer diameter of a portion of the catheter 90. In this way, sleeve 120 slidably engages catheter 90. In an embodiment, the diameter of the sleeve lumen 122 in the unstressed state may be equal to or less than the outer diameter of a portion of the catheter 90. Advantageously, sleeve 120 may slidably engage catheter 90 with an interference fit. In this way, in use, a clinician may pass catheter 90 through sleeve lumen 122 to slidably engage catheter 90. The clinician may position catheter lock 100 in a first longitudinal position on catheter 90. The sleeve 120 may engage the catheter 90 with an interference fit to maintain the position of the catheter lock 100 in a first longitudinal position relative to the catheter 90 until the catheter lock 100 is repositioned by the user to a second longitudinal position.

Advantageously, the sleeve 120 may prevent the conduit lock 100 from sliding off the conduit 90 and contacting a floor surface or the like. Advantageously, the sleeve 120 may be formed of a compliant material and may be compressed between the catheter 90 and the catheter lock 100 to provide an increased grip therebetween. Advantageously, the second material of the sleeve 120 may provide an increased coefficient of friction to provide an increased grip between the catheter lock 100 and the catheter 90. This is particularly important in the naturally moist environment of subcutaneous placement.

In an exemplary method of use, as shown in fig. 4A-4D, a catheter lock 100 is provided as described herein. Initially, the distal end of the catheter 90 may be placed at a target location within the patient's vasculature. Optionally, as shown in fig. 4A, the proximal end 94 of the catheter 90 may be trimmed to a suitable length. The proximal end 94 of the catheter 90 may be fed through the lumen 122 of the sleeve 120 to slidably engage the catheter lock 100 with the catheter 90 when the catheter lock 100 is in the open position.

In an embodiment, as shown in fig. 4B-4C, the catheter lock 100 may engage the catheter 90 with an interference fit. In this way, the user may position the catheter lock 100 in a first position along the longitudinal length of the catheter 90, and the catheter lock 100 may remain in place until repositioned by the user. The user then pushes the proximal end 94 over the rod 60. The user may then reposition catheter lock 100 to be longitudinally aligned with a portion of shaft 60, a proximal portion of catheter 90, or both.

As shown in fig. 4D, the user may then transition the catheter lock 100 from the open position to the first closed position by applying opposing radially inward forces along an axis extending perpendicular to the central longitudinal axis 80 of the catheter 90. For example, a first force of opposing force may be applied to the first portion 112 of the catheter lock body 110 and a second force of opposing force may be applied to the second portion 114 of the catheter lock body 110, causing the first portion 112 and the second portion 114 to rotate relative to one another.

The latch mechanism 140 may engage the first portion 112 and the second portion 114 and retain the catheter lock body 110 in the first closed position. Alternatively, the latch mechanism 140 may be configured to selectively disengage one of the first portion 112 or the second portion 114 to allow the catheter lock body 110 to transition from the closed position to the open position.

In an embodiment, as shown in fig. 3, the latch mechanism 140 may be an over-center latch mechanism 140 configured to couple the first portion 112 to the second portion 114 in the second closed position. The lever of the latch mechanism 140 may be configured to provide a mechanical advantage and then transition the first and second portions 112, 114 to the first closed position and retain the catheter lock body 110 in the first closed position until selectively released. In an embodiment, the diameter of the channel 116 in the first closed position may be smaller than the diameter of the channel in the second closed position.

In embodiments, the diameter of the passage 116 or the diameter of the sleeve lumen 112, or both, may be equal to or less than the outer diameter of the catheter 90. In embodiments, the diameter of the passage 116 or the diameter of the sleeve lumen 122, or both, may be equal to or less than the outer diameter of the portion of the catheter 90 disposed over the shaft 60. In this way, in the closed position, the catheter lock 100 may compress the catheter 90 onto the shaft 60, providing a secure fluid-tight seal therebetween.

Although certain specific embodiments have been disclosed herein, and while these specific embodiments have been disclosed in detail, these specific embodiments are not intended to limit the scope of the concepts provided herein. Other adaptations and/or modifications may occur to those skilled in the art and are intended to be included in the broader aspects.
